📜 A Poem about the Asteroid

DE:
Ein Brocken Gestein, so alt und kalt,
Der Asteroid, durchs Dunkel wallt.
Zwischen Mars und Jupiter zieht er die Bahn,
ein stiller Zeuge vom Weltenplan.
Manchmal kommt er der Erde nah,
dann schaut die Forschung ganz genau da.

EN:
A chunk of rock, so old and cold,
The Asteroid, through darkness rolled.
Between Mars and Jupiter, it draws its path,
A silent witness to the cosmic math.
Sometimes it comes near Earth's embrace,
Then research looks closely at its face.

aus Stein und Metall, kann man mich kneten?

zwischen Mars und Jupiter auf jeden Fall.

• The Asteroid Belt: Most known asteroids reside in the main belt between the orbits of Mars and Jupiter. Der Asteroidengürtel.
• Size: Asteroids vary greatly in size, from a few meters to hundreds of kilometers in diameter (e.g., Ceres, now classified as a dwarf planet). Die Größe variiert stark.
